Sander, check out this website: www.madenterprise.com

That's a site run and operated by Mike Dunn who has developed a transplant kit for L engines into non-SVT F150's.

Here's the kit: http://www.madenterprise.com/scparts.htm

Mike is good people, and I'm sure if you dropped him an email with some questions, he'd be more than happy to help you out.
